Homoscedasticity describes a situation in which the error term or variance or the \"noise\" or random disturbance in the relationship between the independent variables and the dependent variable is the same across all values of the independent variable. In other words, there is a constant variance present in the response variable as the predictor variable increases. If the \"noise\" is not the same across the values of an independent variable, we call it heteroscedasticity, opposite of homoscedasticity. \n", + "\n", + "#### Residuals\n", + "\n", + "Next we apply residual expression to 'price' and 'enginesize' varibles in order to check this assumption.\n", + "[The residuals function](https://l12.xyz/x/shortcuts/src/branch/main/expr.ts) uses mean squared." + ] + }, + { + "cell_type": "code", + "execution_count": 18, + "id": "fc9a31c3-6ac0-4058-b5bb-341eb1c40dd1", + "metadata": { + "editable": true, + "slideshow": { + "slide_type": "" + }, + "tags": [] + }, + "outputs": [ + { + "data": { + "image/svg+xml": [ + "−10,000−8,000−6,000−4,000−2,00002,0004,0006,0008,00010,00012,00014,000↑ price100150200250300enginesize →" + ] + }, + "execution_count": 18, + "metadata": {}, + "output_type": "execute_result" + } + ], + "source": [ + "import { residuals } from 'https://l12.xyz/x/shortcuts/raw/expr.ts'\n", + "\n", + "let residualDf = df.select(\n", + " 'enginesize', \n", + " residuals(pl.col('enginesize'), pl.col('price'))\n", + ")\n", + "\n", + "let residPlot = Plot.plot({\n", + " x: \"enginesize\", \n", + " y: \"price\",\n", + " marks: [\n", + " Plot.dot(residualDf.toRecords(), { x: \"enginesize\", y: \"price\"}),\n", + " Plot.ruleY([0], {stroke: '#ccc'})\n", + " ],\n", + " document\n", + "})\n", + "\n", + "await display(residPlot)\n" + ] + }, + { + "cell_type": "markdown", + "id": "29a0ec4e-084c-4af6-9af6-a14ae5cee4e7", + "metadata": { + "editable": true, + "slideshow": { + "slide_type": "" + }, + "tags": [] + }, + "source": [ + "From the above plot, we can tell the error variance across the true line is dispersed somewhat not uniformly, but in a funnel like shape.
